Increased IOP can cause damage to the visual field and is known as:
Glaucoma
The Dictionary of Visual Science defines this as “the area or extent of physical
space visible to an eye in a given position.”
Visual Field
APD is sometimes confused with
HIPPUS
Fundus Photography takes color photos of the fundus which contains
Retina, Optic Disc, Retinal Vessels
The absence of retinal receptors form:
Scotomas
Testing a patient’s visual field by moving a target through the patient’s visual field
(meridian-by-meridian) is known as
Kinetic Testing
Fundus cameras are normally used to take:
Internal Retinal Photos
Every point on the visual field corresponds to a point on the:
Retina
Which piece of equipment is used to provide a stereoscopic, magnified view of the
eye?
Slit Lamp
The instrument used to measure the curvature of the cornea is known as:
Keratometer
The measurement of intraocular pressure is known as:
Tonometry
When performing applanation tonometry on a patient which filter is used?
Blue
The aqueous filled space between the iris and the innermost corneal surface is
known as:
Anterior Chamber
IOP is caused by the production of:
Aqueous Humor
When performing applanation tonometry, a reading is taken when:
The inner edges of the two semi-circles touch
Deep Anterior Chamber Angle exihibits a dark aqueous section:
1/4 to 1/2 the width of the White section
Glare may distort a patient’s vision causing
Photophobia
The visual field of boths eyes forms an oval that extends approximately
210 degrees laterally and 135 degrees vertically
Two methods to measure the IOP (intraocular pressure) are:
Applanation and Indentation
The Potential Acuity Meter tests visual acuity for patients with
Cataracts
Testing for APD requires:
Dim Room Lights and a Transilluminator
The cornea supplies approximately how much of the refractive power of the eye?
2/3
The Amsler Grid helps to evaluate and monitor
Macular degeneration
While performing applanation tonometry, the slit lamp light should be set:
Fully Open (A circle)
Checking the Anterior Chamber Depth requires the slit lamp ligh to be set:
As a Slit
Narrow Anterior Chamber Angle exihibits a dark aqueous section:
Dark anterior section is less then 1/4 the width of the
white section
Common Beta-Blocker Names
Timoptic (Timolol)/ Levobunolol/
